The double roller granulator is a new generation of compound fertilizer granulation equipment developed by our company. It adopts non-drying room temperature process generation type, with output of 1-1.5 ton-hour and 1.5-3 ton/hour. The equipment has low investment, quick results and good economic benefits. The complete set of fertilizer production line equipment has a compact layout, scientific and reasonable, and advanced technology. Energy saving and consumption reduction, no three wastes are discharged, stable operation, reliable operation and convenient maintenance. The raw materials have wide adaptability and are suitable for granulation of various raw materials such as compound fertilizers, medicines, chemicals, feeds, etc., and the product granulation rate is high. It can produce various concentrations and various types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.) compound fertilizer. The double roller granulator is also suitable for npk fertilizer production lines.

1. Add qualified raw materials to the high-efficiency mixer and mix evenly
2. It is transported to the disc feeder, and the iron material in the material is removed during the transportation process.
3. The material in the disc feeding bar enters the extrusion granulation bar evenly, and the material is forced to pass between the two pressure rollers to be squeezed into flakes, and the flakes are broken into pieces by the coarse crushing bar under the pressure rollers. Screening; the materials on the screen continue to be crushed and screened
4. The semi-finished products are transported to the finished product screening machine; the fine particles after screening are directly returned to the disc feeder; the large particles are crushed by the pulverizer and then returned to the disc feeder
5. The qualified products after screening are transported to the fully automatic packaging scale for weighing, packaging, and storage.
